When ever i use the tools for drawinbg i am not able to get the snap on end points accurately making it very difficult to work on designing. also the circle tool gives weird shapes. i am using iMac M1 with Mac OS sequoia 15.4.1
New or old graphics engine?
Try switching, then restarting SketchUp and seeing if that helps.
I am assuming your forum profile is wrong - if you have an M1 you do not have an NVIDIA graphics card. Upgrade to 2025 - there were quite a few bug fixes related to graphics.
Is your model very far from the model origin point?
